เครื่องโฟโตมิเตอร์-เหล็ก, พีเอช (Iron and pH Photometer)

HI 93743

Iron and pH Photometer with 555 nm LED

          pH is normally measured using litmus paper or pH meters with electrodes. The former is quite inexpensive, but it provides poor results. Litmus paper also poses a serious problem to those who find it difficult to distinguish certain colors. Conventional pH meters, on the other hand, provide very accurate results but the electrodes require maintenance and their price tag is much higher.

There is a third choice. In fact with HI 93743, you can measure pH in a few short and quick steps. The measurements are also impervious to temperature variations, a common source of error with conventional pH meters.

HI 93743 can also measure iron, a prime cause of unpleasant taste in drinking water and damage to kitchen ware and laundry.

With HI 93743, you can now measure both of these parameters with unparalleled accuracy for a cost-per-test that is comparable with chemical test kits and litmus paper.
